V rent is located between adjacent turns 'of the coil as the coil isbeing formed. The conductor of electric current is desirably also ofribbon form either inseparate strips preferably located abreast and ofarcuate formation in the final product or continuous as is the ribbon ofinsulating material, the two ribbons being then intertwined in the finalproduct. v A terminal orlterminals may ex tend laterally into theconductor into con- .2 nection with the electric current conductingportion or po'rtionsthereof. The conductor of my invention has a widevariety of uses among which is its employment 'as an insulated bus barthrough the insulating portions of which terminals are passed intoconnection with the electric current conductingportion or portionsthereof. Thes terminals may be in the form of hooks which may suspendanodes in an electroplating bath.

' The invention will be more fully explained inconnection with theaccompanying drawj- 'ing in which Fig. 1 is a pers ective view of oneform of'conductor; and ig. 2 is a sectional view on line 22 of Fig. 1,on a larger scale. 7 7 I In producing'the insulated conductor, theribbon of insulation 1 is wound in spiral I' fashion upon a mandrelwhich defines the 'bore 2 .of the insulated conductor which'is'-40hollow.'

After the conductor ment 12 has been formed, it is provided withterminals 13 extending laterally therefrom the i .7 tions 12 of theinsulated conducton. ere 7" the conductoris. to be employed forsuspendin anodes in an 'electro lafingbathntstermb 18 may be of hookormatron. As I have ectric current conductingportion or withits marina@16 and rojecting thereinto into connection with g 5 r-. body applied tosaid terminal and dis in said practiced my invention, the holes throughthe conductors 12 and the holes in the ribbon of insulation thatregister with these other holes are larger than the terminals wherethese terminals-are surrounded by theconductor and insulating ribbon,tin or solder 14 being poured into the space that intervenes betweeneach terminal and thesurrounding gibbon and conductor portions wherebythese con-' ductor portions are effectively electrically connected 'withthe terminals. The holes through which each terminal extends desirablyoccur until the bore 2 is reached, so that the solder or tin 14: mayflow into the bore and surround. the inner ends of the terminals 13 toform anchoring knobs or bodies 14' 05 thereon;

It will be observed that thinconductors 12 are thoroughly encased withiinsulation so as to be inaccessible to the electrolyte of anelectroplating bath when such a conductor is used to supportelectroplating anodes.

The current conducting metallic hooks 13 may be replaced from time totime when they grehsufliciently consumed by the acid of the at Y i Whilethe'insulated conductor of my invention is of particular useinconnection with electroplatinequipment, it is obvious that it may have0t er important uses and the ,invention is not, therefore, to be limitedto any particular use to which it maybe put.

Changes may be made without departing from the invention. Having thusdescribed my invention, I claim: An insulated conductor comprising a ribbon of insulating material spirally wound into a coil having a hollowbore, an electric current conductor disposed between adjacent I turns'ofthe coil, a terminal extending trans- .versely of the insulatedconductor into said bore and having electric connection with saidelcct'ric'current conductor, and an anchoring In witness whereof, Ihereunto subscribe my name.
